Highest expected volatility

[drukes1234]

Is there any way to list the stocks that have the highest expected volatility based on options pricing? I'm primarily interested in this to gauge how much options players are expecting a stock to move on an earnings report or any other catalyst. How can I calculate the expected volatility of a stock going into earnings or is there a site that ranks them?


Thanks

Take a look at livevol as well, probably the best stuff I have used in the retail world
